BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 349,395, datedSeptember 21, 1886.

Application filed March 9, 1885.

To all whom it may concern:

Be it known that I, CORNELIUS N. HORTON, a citizen of the UnitedStates,residing at Peeks kill, in the county of WVestchester and Stateof New York, have invented certain Improvement in Brick-Machines, ofwhich the following is a specification.

My invention consists of improvements upon a machine that has long beenin use and has many merits as a horse-power machine; but attemptsheretofore made to adapt it to steam-power have proved failures; and theobject of my invention is to overcome those defects that have preventedits being an acceptable steam-power machine.

The reason why steam cannot always be applied to a machine that willperform well with horsepower is that obstructions that will cause ahorse to stop in its travels with the sweep will, with steam-power,cause a breakage of some part of the machine, since the steam-powerapplied usually far exceeds that of the horses used, and cannot beeither controlled or trained as can the horses.

I attain my object by means set forth in the following drawings, inwhich similar letters refer to similar parts throughout the severalviews.

Figure 1 is a side elevation of a brick-machine, showing the applicationof my improvements. Fig. 2 is a side view of my haul-outtrippingmechanism. Fig. 3 is an edge view of a connecting-rod. Fig. 4 is an edgeview of the connecting-rod used in the haul-out combination, and Figs. 5and 6 relate to improvements in my haul-out mechanism.

A represents the mud-shaft of the machine, and stands in the center ofthe square box E, of which A A constitute two of the cornerframing-timbers, and A is the plank bottom of said box, resting oncross-timbers A between the corner timbers. Crown-wheel B imparts motionthrough pinion O to the cam D. Vipers on the lower end of the mud-shaftforce the clay from the box E into the iron chamber F, which is securedto the front of the machine, and of which the drawings give an end view.Aplunger moves up and down in this chamber, actuated by theconnectingbar a.

mold rests beneath the chamber on the rollers c c and just fills thespace there shown.

Bar a is connected by its lower end to a cam, b, on the square shaft,one end of which shaft is shown at 0. Upon this same shaft thepressure-leverG is secured. This lever I construct substantially asshown. Heretofore the slot as was made so short that the machine couldnot be entirely stopped delivering clay unless the machine was stopped.The notches 1, 2, and 3 shown near the base of this slot are designed toreceive a pin that passes through the bifurcated end of the long pitmanH. This pitman is connected at its upper end with a. crank-pin, j, incam D, and extends downward on both sides of lever G, as may be seen inFig. 3, and as the cam or crank lifts the pitman H the extent of thethrow of lever G will depend upon the notch in said lever, whether in 1,2, or 3, with which pin 1; in pitman H engages. If with notch 1, ofcourse the movement of G will be less than if engaged in 3the notchwhere it is now shown to be caught. It will be plainly seen that theupward movement of G will cause a reverse movement of cam b, and aconsequent downward movement f the plunger in chamber F, which fills themold below with clay, so it will be seen that the varying movementsgiven to G varies the amount of pressure upon the clay in the mold, thusadapting the pressure to the temper of the clay.

After the mold is filled it must be pushed forward from beneath chamberF to the platform f. WVhile this mold is being filled an empty mold isinserted/from the opposite side of the machine from that represented inthe figure, just back of the filled mold and forward of a bar whichoperates upon a rock-shaft. Rod 1' is connected at one end with this barinside of the machine, and outside with arm h, which is secured to shaft70, and is supported on bearings secured to the front corner timbers,one end of a j ournal-box being visible at-l. Secured to this shaft,also, is the lever m, which may be traced by dotted lines to itsconnection with rod on. The upper end of rod n is connected to the leverJ. This lever is pivoted at o, and has its outer end hinged toconnectingrod K, which is hinged at its upper end with lever L. Thislever is pivoted at one end at q, and has abearing, r, at its other end,which admits of free movement up and down only. About midway between theends of this lever I place a friction-roller, 8, calculated to engagewith cam D.

Now, when a mold is filled with clay and an empty mold is in place, camD operates to depress the lever L, which, through K, depresses one endof J, lifting its other end and rod 12 and the lever m, which throws hforward, and i, with the bar at the inner end, pulls forward the emptymold, driving the follower ahead of it to the platform f, when cam D,receding, permits these parts to fall back ready for the next mold. As acounterbalance, and to aid the several parts to resume a normal positionof rest, a weight, w, is'attached to rod a. If, now, an obstruction-suchas a stone-has found its way into the mold to prevent its removal, theundue pressure will automatically trip the haul-out combination. Thecenter of fulcrum 0 should be a trifle to the right of the center ofshaft 7, when any unusual pressure upon K will overcome thecounterbalaneingweight WV, causing it to ascend against the stop 9, ashereinafter described. Lever at is attached to weight WV, which in turnis secured to arm 5, which is secured to an angle-iron, 6. Thisangle-iron may be traced by the dotted outlines. It is pivoted on shaft7, and has an arm, 8, extending upward, and this arm carries the pivotor fulcrum on which lever J is suspended- 7 has a bearing, 2, next theframing of the machine, as will be seen by reference to Fig. 2, and alsoan outer bearing, 2". This outer bearing has an upward extension, 2, theobject of which is to form an outer support for pivot 0, as shown inFigs. 1 and 2. To give a firm foundation to 2 and 2", I extend the plankfoundation to 2 and 2. I extend the plank bottom of box E, as at A andbrace it withbrackets 3 and 3". It will now be seen what effect isproduced by throwing up the le- -ver 4 when an obstruction prevents thedelivery of amold. WeightW falls against the stop 9, and pivot 0describes the are indicated by dotted line 10. This lowering of fulcrumohas the effect of lowering lever L beyond the reach of cam D, and thehaul-out becomes inoperative. Pulling weight \V back to its stop 4.restores the combination to normal position again. When the haul-out isstopped, it is of course important to stop the further discharge of clayfrom chamber F. This is effected by releasing pitman H from its hold onlever G, which operation I will now describe.

By reference to Fig. 3, which is a top view of G and the levers itsupports, except m, which is not here shown, it will be seen that lever1 is divided at its lower end, so as to find a bearing 011 each side ofG, while its upper end projects through and beyond the top edge of thelikewise forked lever 1. A pin passes through 1 at 1 and by means ofthis pin this lever is connected to pitman H at t by con- Another pin,a, through 1 is meeting-bar t.

adapted to catch in notches in the under faces of lever 1 Lever 1? isextended into a handbar toward the front of the machine, and has itsother-end pivoted to an extension of G at 'w. Now, it will be obviousthat if lever 1 be raised from the position now shown pin a will bereleased and the weight of the pitman II will cause it to fall back fromits engagement with notch 3, and, instead of lifting the lever, pin 12will travel in the slot 00, and hence op eration of the press willcease.

Lever x (which is not shown in Fig. 3, to avoid confusion, but is shownin Fig. 1) is pivoted to the outer end of lever 1 at one end,

and its otherend is made circling for a good hand-hold, and has an eyewhich slides over the small end of lever 1 If the present position ofpin 12 of pitman H should require to be changed from notch 3 to notch 2or 1, it can be done without stopping any part of the machine by simplygrasping m, lifting it to free i 1 from pin a, and by pulling it forwarddraw uinto the desired notch, and by dropping this lever 011 pin itagain the change has been accomplished. So, after the pressing mechanismhas been stopped, it can be at once set in motion by lifting and pullingforward lever 00,- but to insure the engagement of pitman H and lever Gat a time when no mischief can ensue, a safeguard is provided.Connecting-bar t is furnished with a projection, y, and the lever G witha curved projection, Then a of pitman His traversing slot as, thisprojection 3 travels within the are provided by 3 and cannot be broughtforward untilv arrives at the point for approaching the notches l 2 3.

My method of making connecting-rod K. is set forth in detail in Fig. 4.,in which B- is an edge view, and B a cross-section through line b. Imake the rod in two pieces, the half 11 at its jointed end beingprovided with short flanges beveled at the inner edges to receive theeorrespondingly-beveled part of I), as shown more clearly at I/. Byusing this flange I am enabled to use a single bolt to secure the twohalves together. At 0 is shown a slot formed for the reception of awedge-like key, as seen in Fig. 1, by which the length of the rod may bevaried to the fraction of an inch.

I wish now to refer to the rod '5 of the haulout combination. The oldmethod of making this rod is shown at Fig. 6, in which z" is the baroperating back of the molds, and which is carried upon arms similar toh, Fig. 5. Through this bar an eyebolt, j, was inserted, as shown,provided with a nut and long thread for adjustment of length of bar 2'.Then by means of a chain-link, 7c, and an eye on the end of the bar theconnection was complete, as shown. The result was a combinationconstantly wearing and stretching. Fig. 5 will show how I attach the bar23 by an eye directly to a pin in h, and then by a long nut and rightand left hand threads on the two inner parts of the rods I have a rodthat is firm and adjustable at any time from the front of the machine.

As constructed heretofore, bar (Z has been IIO 5 the frame, I bring thebar d directlyzin front of post A, thus removing it from all liabilityto damage. A similar bar acts upon the opposite side of the machine. Toavoid setting chamber F ineonveniently far forward, I mor- IO tise out Aa trifle to accommodate bar d, as

shown by the dotted line at the upper end of the bar.

Having fully described my invention, What I claim, and desire to secureby Letters Pat- 15 cut, is

1. The combination, in a brick-machine pressing -mechanism, asdescribed, of the leversG, 1, 1 and w, pitman H, and rod t, united andoperating together substantially in 20 the manner described.

2. The pitlnan H and rod t, provided with arm y, combined and operating,as described, with levers 1 1 x and the cam G, provided with projection3/.

3. In a brick-machine press-tripping mechanism, the combination,substantially as sh own, of the bifurcated lever 1, pin it, notchedlever 1 and hand-lever m.

4. In a brick-machine haul-out, the combination of cam D, roller 8,lever L, connecting rod K, lever J, rod n, lever m, arm 71, and rod i,united and operating substantially as set forth.
